Hello World!
I'm talking about calculating a tip in Alice3.
The Mad Hatter, uh,  says to the Queen of Hearts
"How much tip should I leave?"
And we're going to have a variable
and it will be a double because money is always double.
And this would be the cost of the meal,
And  give it an initial value of anything.
And then going to go to the Queen of Hearts
and she's going to get a double from the user.
And the custom text string is going to be
"How much did the meal cost?"
and then we're going to have a variable, also a double,
called tip, with an initial value of  whatever.
And then were going to replace that by
cost of the meal and were going to add a little math to that.
times a custom decimal number
and I'm going to calculate 15%.
But, 15%, we multiply by 0.15.
And then the Queen will say...  go back to procedures
"You should leave about, a $, and then say OK.
And then were going to add to that the double tip.
And let's run that.
"How much did the meal cost?" Let's make it $20.
And the Queen says, "You should about three dollars."
And again we need to make the duration just a little bit longer,
to give us time to... and let's make it $10 this time.
she says, "You should about 1.5", it doesn't format those numbers.
But that's it, that's all we have to do.
